SOURCE: check engine light on 2003 toyota tacoma, O2 sensor?

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

I am replaceing my existing o2 sensor with a bosch oe smartlink universal sensor. the existing wires are brown/yellow, gray, pink/black. and green. how do I wire the new sensor to the old wires?


you need the factory color code and the bosch color codes.
then wire per that. there is no other way. (universal)
that is the penalty for not using a PNP sensors, plug and play.
do not mess up,wiring the 1 heater to the CELL + wire
risks blowing out the senor or ECU. a $500 error.

here a list. 89-98 list.
first the bosch list ,with comments. my 91 , just and example.
http://www.fixkick.com/oxy-sensor/bosch-pinout.JPG

all bosch unversals sensors have a paper inside,
and is very hard to read and understand.
my guess is it fails german translations.....
no biggy
your car is a 4 wire sensor.
on my cars 96 , the heater wires are non polar so are much easier. lets do them first.
the bosch color is.white, on my car its blk.
so i wired, bosch white to my cars black. x2
bosch gray is sensor ground, (special) wired to cars white wire.
every year, suzuki changes wire colors, not reading the FSM is FAIL.
and last my Bosch CELL+ pin is black and wires to my cars blue.
O2 are like battery CELLS, and are Polar.
Suzuki changed the blue color like a drunk sailor spends money.
a royal PITA. that is. LOL !

the for sure solution is to look it up in the FSM.
for all wire, find your blue, and win !

see the 9 times suzuki changes here, prior to 2004

http://www.fixkick.com/sensors/OxyGen_sensor_help.html

did they change in 2006, ? Ill never know, as Suzuki is bust here.
nor will i pop for $15 to find out. When my Suz, dies, that be the end.
btw 2: the sensor colors on any suzuki are "NCA". FSM drawings.
no color assigned.
the colors mentioned are HARNESS colors in the sensor side.
suzuki uses many different brands sensors and colors, or reserves the right to do so at anytime. Bosch, NGK, Delphi, etc.
tricky huh? thus the pages , linked.
back in 1996 they should have set ISO standards but did not....

i hope that is not confusing.
but in a nut shell.
1: grab bosch sheet,
2: grab the car schematic, for ECU. (fsm, or alldata, or mitchells)
there is your answer.
no man as the blue wire color on all car or all suzuki;'s
not yet. tell my yours and ill update my records.

Bosch 02 sensor downstream on a 1996 Jeep grand cherokee 4.0 motor. I have no wire harness to match the colors to. bosch has two white, one grey and one black. Jeep has orange/green,black/brown,black/blue...


The two white are the heater
The black the ground
The gray the O2 Sensor output,
you back probe to check Voltage
& Switching Times

The vehicle wiring harness does not have to match
the sensor, BUT -- you need to have the same
connector on the sensor

If you have a universal cut & splice, you have junk,
and we given the wrong part

Get a Bosch or NGK, OEM sensor & just
plug it in
